OPERATION:
• The meter is supplied complete with
a 9V battery. Slide off the battery com-
partment cover on the back of the
meter. Install the battery while paying
attention to its polarity.
• Always remove the electrode protective
cap before taking any measurement. If
the electrode has been left dry, soak
the tip (bottom 2.5 cm) in rinse solu-
tion (M10000B) for a few minutes to
reactivate it.
• Connect the pH electrode to the BNC
socket on the top of the meter.
• Make sure that the meter has been
calibrated before taking any measure-
ments (see Calibration Procedure)
• Immerse the tip (2.5 cm) of the pH
electrode into the sample.
• Turn the instrument on by pressing the ON/OFF key.
• Allow the reading to stabilize before taking mea-
surements.
• After measurements, switch the meter off and
store the electrode with a few drops of storage
solution in the protective cap.
CALIBRATION PROCEDURE:
• Remove the protective cap from the electrode.
• Immerse the electrode tip into a new sachet of
pH7 calibration solution and allow the reading
to stabilize.
• Adjust the pH7 (OFFSET) calibration knob to
display "7.0 pH".
• Open a new sachet of pH4 cali-
bration solution and use a small
quantity to rinse the electrode.
• Immerse the electrode tip inside
the pH4 sachet and allow the read-
ing to stabilize.
• Adjust the pH4/pH10 (SLOPE) cali-
bration knob to read "4.0 pH".
• The calibration is now complete and the meter is ready to
take measurements.
• It is suggested to recalibrate the meter at least once a
month, after a prolonged stocking time and after electrode
replacement.
BATTERY REPLACEMENT:
When the battery becomes weak the
meter will display "V".
When the low battery indicator appears,
the battery has only about 50 hours of
working time left. A low battery will result
in unreliable measurements. It is recom-
mended to replace immediately the
battery.
Battery replacement must only take place
in a non-hazardous area using an alka-
line 9V battery.
Turn the meter off, slide off the battery
compartment cover at the rear of the meter
and replace the 9V battery with a new
one. Make sure the battery contacts are
tight and secure, seat the battery in its
compartment and insert the cover again.
